Application of High-Specific-Surface-Area Calcium Hydroxide in Flue-Gas Desulfurization for Industrial Kilns in the Chemical Industry
In the chemical industry, flue gases from various reaction kilns and heating furnaces are highly complex; in addition to sulfides, they often contain small amounts of acidic organic compounds. These flue gases are highly corrosive, and conventional desulfurization agents exhibit limited reactivity and poor corrosion resistance, resulting in only modest treatment performance. High‑specific‑surface‑area calcium hydroxide can achieve simultaneous desulfurization and deacidification, making it well suited to the complex flue‑gas conditions encountered in chemical processes.

Application of High-Specific-Surface-Area Calcium Hydroxide in Flue Gas Desulfurization in the Refractory Materials Industry
Refractory‑material tunnel kilns and shuttle kilns operate at high temperatures and produce uneven flue‑gas emissions; their intermittent operation further causes significant fluctuations in sulfur content, placing extremely stringent demands on the desulfurizing agent’s instantaneous reaction kinetics and operational adaptability. High‑specific‑surface‑area calcium hydroxide, with its high reactivity and rapid response, is well suited to meet the desulfurization requirements of the refractory industry’s batch‑type production processes.

Application of High-Specific-Surface Calcium Hydroxide in Flue Gas Desulfurization in the Industrial Silicon Industry
The flue gas from industrial silicon smelting furnaces is characterized by high temperatures, extremely high dust concentrations, and abundant sulfide‑containing impurities, resulting in harsh operating conditions. Conventional desulfurization agents are prone to failure, leading to poor desulfurization stability—making this a significant challenge in industrial flue‑gas treatment. High‑specific‑surface‑area calcium hydroxide, with its strong adaptability and excellent penetration, is ideally suited to the desulfurization of flue gases generated during industrial silicon smelting.
